You Rang, M'Lord? is a BBC television sitcom written by Jimmy Perry and David Croft, the creators of Dad's Army. It was broadcast between 1988 and 1993 on the BBC. The show was set in the house of an aristocratic family in the 1920s, contrasting the upper-class family and their servants in a house in London, along the same lines as the drama Upstairs, Downstairs.

The series featured many actors who had previously appeared in earlier works by Perry and Croft, notably Paul Shane, Jeffrey Holland and Su Pollard, all of whom had starred in Hi-de-Hi!; also featured were Donald Hewlett and Michael Knowles from It Ain't Half Hot Mum, and Bill Pertwee and—occasionally—Frank Williams from Dad's Army. Numerous small parts were played by other alumni of David Croft and/or Jimmy Perry shows. The memorable 1920s-style theme tune was sung by comedian Bob Monkhouse.

Episodes of You Rang, M'Lord? were fifty minutes long, rather than the usual thirty (for BBC sitcoms), and attempted to introduce a more reflective approach and more complex plotting than other Croft and Perry series. There was also less reliance on filmed location sequences.
